Mills and unique topography
This low level trail, takes just over an hour and starts at the height of Vilaboa where we took the N-554 to reach the height of Rio Maior. We took a paved trail to the right that leads to the House of Culture of this place, at the trailhead. The place where the mills are situated, has a unique topography, through which flows the Rio Maior. On its banks are a lot of mills that formerly served as grain milling systems, for rye and corn in particular. If you follow the course of the river, there is a beautiful waterfall, known as "The Waterfall of Tras do Rio", and other smaller wones which have a great charm.
